Line

Home

A single line segment having two endpoints only. Lines can be one segment or a series of connected segments, but each segment is a separate line object. Use the line object if you want to edit individual segments. If you need to draw a series of line segments as a single object, use the Polyline object.

To add lines into a drawing use following functions:

Function	Meaning
lcBlockAddLine	By two points
lcBlockAddLineDir	By base point, angle, length
lcBlockAddLineTan	As a tangent between two circles or arcs

A line entity has the following properties:
